short and ends free. A car- 

 tilaginous offshoot from be- 

 low the edge of the clavicular 

 facet extends towards it. 



Incomplete Spe- 

 cimens. There are 5 of 

 fusion of the atlas and occi- 

 put, of which one is probably 

 pathological. There is one 

 from an Egyptian of the 12th 

 dynasty (some 4000 years 

 old) of which the almost ex- 

 act counterpart, except that 

 the side of greatest fusion 

 is reversed, was obtained 

 from the dissecting room a 

 few years ago. There are 

 two cases (not of my col- 

 lecting) of fusion of the 

 axis and 3rd vertebra very 

 much like those described 

 by Leboucq. There are two 

 cases of cervical ribs of little 

 interest, two of a rudimen- 

 tary 1st rib and one of 

 fusion of the 1st and 2nd 

 thoracic ribs. There is also 

 one lateral half of a sacrum 

 which probably had an extra 

 half vertebra on one side. 



Of the deductions that 

 may be made from these 

 specimens, some are of 

 merely morphological inter- 

 est, while others are far- 

 reaching. It is not possible 

 to separate the two groups 

 completely.
